I think it would be good to hear from the libvirt folks (on Cc:) on this as
having QEMU unplug a device without libvirt's involvement seems like it
could cause issues. Personally I think it seems cleaner to just have QEMU
handle the 'hidden' aspects of the device and leave it to QMP/libvirt to do
the unplug beforehand. On the libvirt side I could imagine adding an option
like virsh migrate --switch-to-standby-networking or something along
that line to do it automatically (if we decide doing it automatically is
even needed on that end).

[libvirt] [PATCH] qemu: Add support for postcopy-requests migration statistics
by Jiri Denemark
QEMU can report how many times during post-copy migration the domain
running on the destination host tried to access a page which has not
been migrated yet.

[libvirt] [PATCH v2] qemuDomainRemoveRNGDevice: Remove associated chardev too
by Michal Privoznik
https://bugzilla.redhat.com/show_bug.cgi?id=1656014
An RNG device can consists of more devices than RND device
itself. For instance, in case of EGD there is a chardev that
connects to EGD daemon and feeds the qemu with random data. When
doing RNG device removal we have to remove the associated chardev
as well.

[libvirt] [PATCH RFC v2] qemu: fix deadlock when waiting in non async jobs
by Nikolay Shirokovskiy
Block job abort operation can not handle properly qemu crashes when waiting for
abort/pivot completion. Deadlock scenario is next:
- qemuDomainBlockJobAbort waits for pivot/abort completion
- qemu crashes, then qemuProcessBeginStopJob broadcasts for VM condition and
then waits for job condition (taken by qemuDomainBlockJobAbort)
- qemuDomainBlockJobAbort awakes but nothing really changed, VM is still
active (vm->def->id != -1) so thread starts waiting for completion again.
Now two threads are in deadlock.
First let's remove broadcast in qemuProcessBeginStopJob. It is simply wrong
because it is not set any condition before broadcast so that awaked threads can
not detect any changes. Crashing domain during async job will continue to be
handled properly because destroy job can run concurrently with async job and
destroy job calls qemuProcessStop which sets vm->def->id to -1 and broadcasts.
Second let's introduce flag that EOF is received and broadcast after that.
Now non async jobs can check this flag in wait loop.
Signed-off-by: Nikolay Shirokovskiy <nshirokovskiy(a)virtuozzo.com>
---
Diff from v1:
- patches 1 and 2 are already merged
- don't bother with reporting monitor EOF reason to user as most of
time it is simply "unexpected eof" (this implies dropping patch 3)
- drop patch 5 as we now always report "domain is being stopped"
in qemuDomainObjWait
- don't signal on monitor error for simplicity (otherwise we need to report
something more elaborate that "domain is being stopped" as we don't
kill domain on monitor errors. On the other hand I guess monitor
error is rare case to handle it right now)
- keep virDomainObjWait for async jobs
It's a bit uneven that for async jobs domain is destroyed concurrently and for
non async jobs it will be actually destroyed after job get completed. Also if
non async job needs issuing commands to qemu on cleanup then we will send these
commands in vain polluting logs etc because qemu process in not running at this
moment but typical check (virDomainObjIsActive) will think it is still running.
Domain is destroyed (qemuProcessStop) in a job due to patches [1] and [2].
However AFAIU it is not neccessary. If qemuProcessStop does not drop VM lock
then we don't need extra job to make qemuProcessStop and main job not
interleave. And we can drop the lock now only in qemuDomainObjBeginNestedJob in
qemuProcessStop which is introduced in [2]. AFAIU we can fix issues mentioned in
[2] the other way for example like it is done for qemu agent - we save agent
monitor reference on stack for entering/exiting agent monitor.
So I wonder can we instead of this fix remove job for qemuProcessStop and run
destroying domain cuncurrently for non async jobs too.
